- Abstract
This study was conducted to evaluate the effect of residual feed consumption (RFC) selection on the population genetic structure. Fifty ducks of the Better Feed Efficiency Brown Tsaiya (BFEBT) in the 6th generation and 46 ducks of its control line were investigated by 11 Tsaiya microsatellite markers, and a cross-generation compatison was also conducted with the previous 2nd, 4th, and 5th generations. The results showed that there was no significant difference between BFEBT and its control line in genetic vatiation. The FIS (Wright's fixation index) value revealed that the populations were still not faced with severe inbreeding. There was significant differentiation between these two lines in the 4th and 5th generations (P < 0.05), and the FST values increased with generations of selection. In order to promote the sustainable management of these duck lines, the cross-generational genetic monitoring ·will be carried on continuously.
